I have the following code :

string num = "4D"; // means 77 in dec

Is there away to extract that number as it is and put it in a new variable? I need to get the decimal equivalent of this hex number

`std::istringstream` and `std::hex` should do what you want. – πάντα ῥεῖ Dec 31 '20 at 10:13
```std::stoi("4D", 0, 16);``` see https://stackoverflow.com/questions/11608878/c-convert-string-to-hex – ThatBuffDude Dec 31 '20 at 10:13
